IMPROVEMENT IN APPARATUS FOR TREATING OIALS.

Spccilcation forming part of Letters Patent No. 105,035, dated July 5, 1370.

To @ZZ whom, it may concern:

Be it known that I, THOMAS H. BURRIDGE, of St. Louis, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in an'Apparatus for Treating Oil, of which the following is a description.

In Figure l, A is areservoir for holding the oil to be treated; B, a decolorizing-chamber, C, a generator; D, a refiner; Fig. 2, an inside view of the decoloriziiig-chamber, Fig. 3, a longitudinal section of the same, Fig. 4, a vertical transverse section of the generator, Fig. 5, a vertical transverse section of the reiiner.

Like letters of reference refer to like parts in the different views.

This invention has for its object the refining. and decolorizing of oils for paints by subjecting them to the action of gases, steam, and liquids by the'employment of certain devices, consisting of a reservoir, decolorizer, generator, agitator, and refiner, as hereinafter more fully described.

In the drawings, Fie'. l, A represents a vessel, iu which the crude oil is placed preparatory to its treatment, and from which it is drawn into the decolorizing-vessel B through the faucet ACl The decolorizer consists of a flat shallow pan, of the peculiar shape shown in Fig. 2, which represents the inside thereof, and of which B, Fig. l, is a side view. Transversely across the bottom of the decolorizer is a series of partitions, E, Fig. 2, in depth about one-third that of the decolorizer, thereby dividing it into several narrow and shallow compartments, c, Fig. 3, the whole of which is covered by a wire cloth or netting, F. This decolorizing section of the apparatus is connected to the decolorant generator C by means of the pipes G H, and which in turn is attached to a steam-boiler by means of the pipes I J terminating in the pipe K. Suspended a little above the bottom of the generator is a basin or shallow dish, L, Fig. 4, which is of less diameter than that of the generator, thereby leaving a narrow space, b and c, around and below the dish, as shown, the purpose of which D, Fig. 5, is a renner, consisting of a cylindrical-shaped vessel, having vertically therein a tubular shaft, M, provided with a series of tubular radial arms, N. Said shaft is put in open' connection with a pipe, O, and by means of which it is connected to a steam-boiler for the reception of steam.

Having thus described the construction and arrangement of the apparatus, the practical operation of the same is as follows: As above said, the oil to be refined is put into the vessel A, from which it is allowed to iiow slowly into the decolorizer B, the amount being graduated by the faucet A as the oil slowly enters through the perforationse of the transverse distillatingpipe P. Itis atomized by spreading over the wire-gauze F in a thin film, and by percolating through it, at which time it is then charged with and acted upon by decolorants, generated by the generator G, from which vessel the decolorant gases or iiuids are conducted to the decolorizer by the pipes G H. In connection with the decolorant agents employed, a jet of steam is used, which is received into the generator from a steam-boiler, to which said generator is attached. From the generator it is forced into the decolorizer, and, in combination with the decolorants, which may be either fluid or gaseous, or both, it attacks the oil as it iiows down the incline of the decolorizer, and is therein agitated by flowing over the several partitions E. By this means the coloringmatter of the oil is removed, so that it leaves the apparatus, through the eduction-pipe Q, clear and free of color. The oil, after being thus treated in the decolorizer, is subjected to a further treatment as a refining process. Thus it is placed in the refiner D, which is asteamtight cylinder attached to a steam-boiler by means of the pipe O, and through which4 steam at a temperature not exceeding 212 is admitted. The hollowshaft M and tubular arms, constituting an agitator, is now made to revolve, thereby violently agitating the oil, and

at the same time discharging into it jets of steam from the radial arms N. The oil, after being thus treated for some thirty minutes, is allowed to rest. The impurities and mucilaginous matter therein will be deposited on the surface of the water below the oil after standing some four or five hours, which may then be drawn 0H through the faucet R, Fig. 5. The oil remaining below the faucet may be drawn off by injecting water into the agitator through the faucet' S, thereby raising the oil, so that it will iiow from the higher faucet, above described.

By this arrangement and co-operation of the devices in the manner as above described, oils,

y though of high color and of great impurity,

can be quickly and thoroughly bleached to a pure white color, and refined from all impurities, thus fitting them for practical use in the arts requiring colorless and refined oils.

What I claim as my improvement, and desire to secure by Letters Patent, is-

l. The deoolorizer, Fig. 2, consisting of the pan B, partitions E, transverse distributingpipe P, and wire-gauze F, substantially as described, and for the purpose specied.

2. The decolorant generator C, as constructed and arranged in relation to and in combination with the deeolorizer, Fig. 2, to co-operate therewith, in the manner as described, and for the purpose set forth.

3. The refiner, Fig. 5, consisting of a cylinder, D, tubular shaft M, radial tubular arms N, and faucets R S, all arranged to operate in the manner as described, and for the purpose speciiied.
